[CentOS] fail2ban problem

I run strace -s 512 -f -F -p 9406
9406 is fail2ban-server pid

9406  poll([{fd=3, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}], 1,
30000) = 0 (Timeout)
...

I think that the problem is not in server but the way actions "attached"
to iptables.
Python maybe?

Thanks again...
